VENEER S'LICING AND SCORING MACHINE.

Application filed December 3, 1918.

Scoring Machines, of which the following is a specification.

This invention relates to a veneer slicing.

and scoring machine.

In the manufacture of veneer, such as is employed in the making of fruit baskets and the like, it has been common practice to slice or cut the veneer in one machine and then to score or partly cutthe veneer along the folding lines in a second machine to permit the veneer to be properly folded when the baskets are being formed. This method is more or less costly and wasteful, first, because it requires two separate machines and operations, and, secondly, repeated handling of the material, thereby causing a decided loss in the cost of manufacture due to the additional labor required and the resultant increase in material damaged.

The object of the present invention is to provide a simple, substantial, easily operated machine for slicing veneer, such as is employed in the manufacture of fruit baskets and the like, which will not only slice the veneer but will also score the same, thereby producing a finished product in one operation, that is, a slice of veneerwhich has simultaneously been scored along the.

folding lines. Further objects willhereinafter appear.

The invention consists of the. parts and the construction, combination and arrangement of parts which will be hereinafter described and claimed, having reference to the accompanying drawings, in which Figure l is a side elevation of the machine.

Fig. 2 is a perspective view of a slice of veneer which has also been scored.

Fig. 3 is a section'on the line 33 of Fig. 1.

Fig. 4 is a plan view of Fig. 1.

Referring to the drawings in detail, A indicates the base of the machine, which, in this instance, supports a pair of guide rails 2 and 3. One of the rails is supported di- Specification of Letters Patent.

rectly onthe frame A, while the opposite rail 3 is supported by 'a pair of arms 4 formed as an integral part of the main frame A. The rails 2 and 8 are positioned on an angle of 15 and are provided for the. purpose "of supporting and guiding a rectangular shaped frame 5 to which recipro- Patented Jan. 13, 1920.

cal movement is imparted by means of a] link 6'and a'crank 7, the crank 7 being secured on a shaft 8 supported in a journal 9 and driven by means of a pulley 10.

The frame 5 is provided for the purpose of supporting a slicing knife 10 and a pair of scoring knives 11. The slicing blade is secured by means of screws 12 to a cross bar 13 rigidly secured on the frame 5 to permit the blade to be readily removed forv resharpening, repairs or otherwise. The scoring knives 11 are supported in arms 14 formed as integral parts of sliding blocks 15. These blocks are supported between guide rails 16, both of which are rigidly secured on a plate 17 carried by the frame 5. Also formed as an integral part of the sliding blocks 15 is a pair of guiding arms 18. These arms straddle cam members 19 which are carried by a bracket plate 20 secured, as at 21, to the main frame A. Reciprocal movement imparted to the frame 5 will therefore cause the knife 10 to move in such a manner that it will produce a drawing out across the block 22, from which the veneeris sliced, and it will simultaneously impart a reciprocal movementto the sliding blocks 15 which will cause .the scoring knives 11 to pass across the face of the veneer along converging lines, such as shown at 23 (see Fig. 2), as will hereinafter be described.

The block from which the veneer is to be out has a cross sectional formation, as

shown in Fig. 2. This block is supported on a feed table 24 in front of a slidable backstop. Said table is formed as an integral part of the main frame A, movement being imparted to the back-stop by means of a pair of rack bars 26, pinions 27 secured on a shaft 28 and a hand crank 29.

In actual operation, referring to Figs. 1 and 3, it will be seen that it is only neces sary to place the block 22 upon the feed table 24. A back-stop 30 on the table forces the block forwardly against the plate 17 carried by the sliding frame, This plate latter.

therefore not only serves as a support for the scoring knives, but also as a stop plate for the block from which the veneer is sliced. The reciprocal movement imparted to the frame 5 therefore causes the knife to travel across the face of the block 22 in such a manner that a drawing out is produced. This is due to the fact that the frame 5 travelson an angle of 45, while the knife 10, together with the block 22, is standing in a horizontal position. The downward movement of the frame 5 furthermore pulls the scoring knives 11 across the face of the block, and, as said knives are carried by the sliding blocks 15 and these are in turn moved toward each other, due to the fact that the arms 18 embrace the cam members 19, it can readily be seen that the face-of the block is first of all scored on the converging lines shown at 23 (see Fig.2), and, secondly, that the slicing knife 10 will cut the veneer.

The movement of the knife 10 is limited so that when the lowest position is reached the block 22 or veneer slice will just be cut.

The cutting edge of the knife 10 will there fore just reach the surface of the table 24 and will therefore not have a tendency to break the lower edge of the block 22 and produce a ragged edge. A wooden filler plate may be placed on the table to permit the first stroke of the knife to partly enter the same, thus further insuring a clean cutor slice after each reciprocation of the knife and frame 5.

While a crank arm 29 is provided for the purpose of operating the feed table I wish it understood that any other feeding mechanism may be employed; similarly, that the materials and finish of the several parts forming the machine may be such as the eX- perience and judgment of the manufacturer may dictate.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
